JEROME WALSH AND ELIJAH A. WALSH, OF WALSHVILLE, NEW YORK.

MEANS FOR BURhliNG BEHCKS OR THE LiitlE.

SPECIFIGATIOIiT forming part of Letters Patent No. 747,283, dated December 15, 1903. Application filed March 25, 1903. Serial No. 149,416. (No model.)

T0 aZZ whom it may concern:

Be it known that we, JEROME WALSH and ELIJAH A. WALsH, citizens of the United States, residing in Walshville, in the county of Columbia and State of New York, have jointly invented certain new and useful Improvements in Means for Burning Bricks or the Like, of which the following is a specification.

This invention relates to means employed in burning ceramic materials, and particularly to burning bricks in what are known as open-air kilns; and the invention resides mainly in the improved furnace and connections employed.

In the accompanying drawings, which serve to illustrate an embodiment of the invention, Figure l is an horizontal section of the kiln of bricks taken through the arches, the furnaces and connections being seen in plan. Fig. 2 is an end elevation of the kiln and furnaces. Fig. 3 is a side elevation of the same. Fig. 4 is a vertical mid-section of the furnace on a largerscale than the principal views, and Fig. 5is afront elevation of the same. Fig. 6 is afragmentary detail view showing sliding in lieu of hinged doors to the furnace.

K designates the kiln or mass of bricks as a whole,and a the arches therein, said arches extending through from side to side in the usual Way. A kiln of bricks of this kind is well known to those skilled in brick-n1aking; but it may be proper to state that the bricks, first hacked and dried in the sun, are laid up loosely in the mass that is to form the kiln, the arches being produced in the building.

After the mass is formed the four sides of there may be any desired number, according to the size of the kiln, is illustrated in detail in Figs. L and 5 and will be described.

The metal shell 1 of the furnace is lined throughout with fire-bricks or tiles 2, and the bridge-wall 3 is also of like-refractory material.

4 is the grate or fire-bed.

5 is the ash box or pit.

6 is the firebox or combustion-chamber.

7 represents the wheels of the furnace to run on the rails of the track T.

8 represents the charging-doors in the furnace-front, and 9 represents ash-box doors.

Air is supplied to the furnace from a suitable blower B, driven by power. This blower, together with the engineE and the steamgenerator G, are mounted on a platform P, provided with wheels in to run on the track. The track may be the same as that on which the furnaces are mounted; but preferably inorder to keep it properly alined there will be a separate track-rail T laid alongside the track T, and the wheels will run on this rail and the adjacent rail of the track T. The blower connects with the furnaces by an air'supply pipe A, from which extend branch pipes A, which supply the respective furnaces. The pipe A supplies air under the grate 0f the furnace to enhance combustion, and a branch I) therefrom supplies air to the combustion-chamber above the grate. These air-supply pipes are provided each with a damper d. From the back of the furnace a pipe or pipes 0 lead the products of combustion to the arches of the kiln. In the construction as herein illustrated there are three pipes O for the hot gases from each furnace leading to as many adjacent arches in the kiln, Fig. l; but this is not essential to the invention. Each furnace may supply one or more arches of the kiln. For convenience in adapting the apparatus to kilns of different lengths and also for convenience in handling and placing the furnaces the main air-supply pipe A is made in sections, which fit together, so that they may be easily separated-that is, there is one section to each furnace and in order to equalize the distribution of air to the several furnaces connected in series and supplied from the end the supply-pipe A is made up of sections which are gradually reduced in diameter, that section next the blower having the greatest diameter and that at the end farthest from the blower having the least diameter.

There will be ordinarily and by preference two like sets of furnaces, one set at each side RGO ter is built up in the usual way. The furnaces run along the tracks properly placed and connected through the piping, as shown. The blowers are then run into position and coupled to the furnaces. Fires are then started in the furnaces and the blowers set to work.

The branch pipes b force the hot gases through the pipes G into the arches a, from which they rise through the interstices between the bricks and finally escape at the top of the kiln. After the bricks in the kiln are burned the furnaces and blower are moved along the track to a fresh kiln, where they are coupled up and set to work, thus leaving the burned kiln free of encumbrances, so that it may be taken down and the bricks carted away. The

' heat in the furnace will be very intense, and

the forced blast from the branch pipe I) forces the gases while still at a very high temperature into the mass of bricks. There will be thus established a rapid flow of hot gases through the mass of bricks, and not only will much time be saved in the burning over the ordinary methods where the natural draft is relied on, but the temperature throughout the kiln will be more uniform and the bricks be more uniformly burned.

By blower is here meant any air-forcing apparatus or means of compressing or forcing air. There are many devices of this character in the market.

The furnace-doors may be mounted to slide, as seen in Fig. 6, if preferred. In this View the doors 9 are mounted slidably in guides 10 on the front of the furnace.

The pipes 0, leading from the furnace to the kiln, will have or may have in them suitable dampers or cut-off devices 0.

Having thus described our invention, we claim 1. As a means for burning bricks and the like in a kiln, a track at the site of the kiln, a furnace on the track and movable therealong, a pipe for the hot gases adapted for connecting said furnace with the kiln, and an air-forcing apparatus connected with the furnace and supplying a blast of air both above and below the fire-bed of the furnace, said air-forcing apparatus being provided with wheels and movable along its track independ- 6o ently of the furnace.

2. As a means for burning bricks and the like in a kiln, a track at the site of the kiln, a furnace on the track and movable therealong, a pipe for the hot gases adapted for connecting said furnace with the kiln, an airforcing apparatus mounted on wheels on the track and movable therealong independently of the furnace, and air-supply pipes connecting said air-forcing apparatus with the furnace both above and below the fire bed thereof.

3. As a means for burning bricks and the like, in a kiln having a plurality of arches, a plurality of furnaces at the side of the kiln in front of the arches, an air-forcing apparatus mounted on wheels and movable independently of the furnaces, a sectional airsupply pipe connecting said forcing apparatus with the furnaces both above and below the fire-beds of the latter, and pipes for the hot gases connecting the respective furnaces with the arches of the kiln.

4:. As a means for burning bricks and the like, a plurality of furnaces with wheels at the side of the kiln in front of the arches, a track on which the furnaces run, an air-forcing apparatus with wheels, a track on which said apparatus runs, said apparatus being movable along its track independently of the furnaces, a sectional air-pipe A for connecting the several furnaces with the air-forcing apparatus, pipes connecting the sections of said pipe A with the respective furnaces above and below the grates thereof, and pipes extending from the respective furnaces to the arches of the kiln.

5. As a means of burning brick and the like in a kiln having arches extending through it from side to side, two substantially parallel tracks along the respective opposite faces of the kiln, furnaces mounted on wheels on said tracks, pipes for the hot gases connecting the furnaces with the arches in the kiln, air-forcing apparatuses on wheels and movable along the tracks independently of the furnaces, and air-pipes connecting each set of furnaces with its air-forcing apparatus, substantially as set forth.

In witness whereof we have hereunto signed our names, this 20th day of March, 1903, in the presence of two subscribing witnesses.
